CAUTION-1

CAUTION (COLOR LCD)

LCD display; the liquid crystal display (LCD) panel is made by highly precise technology.

More than 99.99% of its picture elements (pixels) are effective, but some (less than 0.01%) may appear as colored

bright dots. This does not indicate a fault as the LCD panel stretches the limits of current technology.

CLASS 1

LASER PROCTECT

CAUTION

This product contains a laser diode of

higher class than 1. To ensure contin-

ued safety, do not remove any covers

or attempt to gain access to the in-

side of the product. Refer all servicing

to qualified personnel.

CAUTION

BLE

LASER RADIATION WHEN OPEN.

AVOID EXPOSURE TO BEAM.

Contents included:

ANA and DIG circuit board diagrams included are for reference during troubleshooting.

This manual does not include the schematic diagrams of ANA and DIG circuit boards, since these boards must be

replaced in units of board and their components are not assigned as service parts.

SHD, RAM2LD and PHD circuit board diagrams included are for reference during troubleshooting.

This manual does not include the schematic diagrams of SHD, RAM2LD and PHD circuit boards, since these

boards are included in the mechanism unit and they or their components are not assigned as service parts.

Many electrical and mechanical parts have special safety-related characteristics. These are often not evident from visual

inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for a

higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this

Service Manual. Electrical components having such features are identified by marking with a

on the schematics and

the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety

characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create

shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from time to time.

For the latest information, always consult the current HITACHI Service Manual. A subscription to, or additional copies for,

HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES CORPORATION.

PRODUCT SAFETY NOTICE

!

Lithium battery; danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type

recommended by the equipment manufacturer. Discard used batteries according to manufacuturer's instructions.

When replacing the lithium battery it is important to use the same type and connect it correctly.

WARNING:

Lithium batteries contain dangerous chemicals.

Handle and dispose of with great care.

Do not throw in a fire.

Do not short circuit it.

For disposal place in a plastic bag and put in waste bin.

Notes When Using Service Manual

The following shows the contents to be noted when using service manual:

1. Value units used in parts list

This table shows locations of each part on circuit board

diagrams. The locations are indicated using the guide

scales on the external lines of diagrams.

1) One diagram indicated for each board

The values, dielectric strength (power capacitance) and

tolerances of the resistors (excluding variable resistors)

and capacitors are indicated in the schematic diagrams

using abbreviations.

[Resistors]

Certain symbols are indicated below for value units of

resistors, capacitors and coils in parts list. When you read

them note the following regular indications:

side.

Side B: Shows leadless parts, viewed from the

pattern side.

2) Board having patterns on both sides and parts on

both sides.

Side A: Shows parts and patterns which can be seen

when the case is opened.
